ATTORNEYS Tatented July 28, 1 931 HARRY BABNOWITZ, OF BROOKLYN, NEW YORKEDUCATIONAL GAME APPARATUS Application filed October 30, 1929. SerialNo. 403,577.

This invention relates to educational game apparatus which constitutesin eiiect a toy which is entertaining and instructive to a child orother user.

A further object is to provide a device of when the child writes 1 thischaracter in which a problem and a pictorial representation aredisclosed, and the proper answer is normally covered so that the answerto the prob- (em he can uncover the proper answer and discover whetheror not his written answer is correct.

A further object is to provide a device of this character in which theouter surface is preferably coated or covered to form what is ordinarilyknown in the trade as a slate so that a slate pencil or chalk can beused sud easily erased after writing on the surace. I

A further object is to provide a device of this character which containson its outer face letters and numerals which will act as a guide to thechild in forming the letters and numerals. i

A further object is to provide a device of this character which can bemanufactured and sold at a low price and'which will constitute a sourceof amusement as Well as resuit in the improvement of the mind of thechild.

' on the line 22 of Figure 1;

- tion of the :V fith these and other objects in view, the inventionconsists in certain novel features of construction and combinations andarrangements of parts which will be more fully hereinafter described and'pointed out in the claim. i

In the accompanying drawings-- Figure 1 is a plan view of my improveddevice; 1

Figure 2 is a view in longitudinal section Figure? is a fragmentary viewof a por intermediate disk of 'the device showing the shutter thereon;

Figure 4: is a complete'plan view of the intermediate disk of-my*T/Vhiie of course a device of this character is portableand may be indifierent positions, we will assume-for purposesof description that itis in a horizontal position so that the metrically.

" the picture improved device.-

be disdisks forming the apparatus may I ower tinguished by terming themupper and intermediate disks.

My improved device comprises upper and lower disks 1 and 2 with anintermediate disk 3 but they are mainly hidden from View All of thesedisks 1, 2 and 3 have a pivot at their centers which connects them andwhich constitutes an ordinary clip 4;, or may be of any desired formwhich permits the intermediate disk to turn or move between the upperand lower'disks,

The upper and lower disks are held against independent movement, andWhile I may employ various means for the purpose I have indicatedtongues 5 at opposite edges of both of said disks 1 and 2 with spacers 6between the tongues, and securing devices 7 securing the tongues andspacing devices together.

8 represents a shutter which is pivotally supported on the device 4 andlocated between the upper disk 1 and the intermediate disk 3, and thisshutter 8 has a finger hold 19 thereon projecting from the periphery ofthe disks and preferably contains the word Answer and can be manuallymanipulated as will be decreinaiter explained, and it will he noted.particularly by reference to Figure 1 of the drawings that the fingerhold 19 is limited in movement in one direction by the spacer 6 hetweenthe tabs 7, and this is the vnormal closed position of the shutter.

The intermediate disk 3 is provided on its upper face with a circularseries of pictures 9 with a mathematical problem 10 adjacent thesame andwords 11 and numerals 12 diaopposite the pictures 9 and prob- ;id.

The upper disk 1 is provided with openings 13 and 14 to expose thepictures and problems and is provided at diametrically opposite pointsclosingthe words and numerals describingand answering the problems.These latter openings 15 and 16 are normally covered by the shutter 8,as clearly indicated in Figure l of the'drawings.

@n the face of the upper disk 1 the letters of the alphabet and numeralsfrom 1 to 10ers preferably provided as a guide to the child withopenings 15and l6 dison the disk,

the proper letters'and numerals and as this disk hasa surface whichconstitutes in effect a blackboard a pencil of chalk may be used and thewriting easily erased.

A tongue 17 projects from the disk 3 beyond the disks land 2 so that bymeans of this finger the disk 3 may be turned.

In operation the disk 3 is manually turned to expose a picture and aproblem through the in writing openings 13 and-14. The child writes theword describing the picture and numeral or numerals indicating the,answer to the prob lem on the surface of the disk 1. He then moves theshutter 8 toexpose the answers so as to find out whether or not thewritten matter is 'correct. He then'moves the'shutter to close theopenings 15 and 16 and turns the disk 2 to present another picture inthe problem, and this operation is repeated indefinitely.

In describing the improved device 1 cmloy the word disk because thepreferable ormation of these parts is circular and relatively thin butit is obvious that this device may be otherwise shaped, and it is to beunderstood thatI do not Wish to limit myself in the claims by theemployment of the term disk as limiting me to a circular form.

Various changes and alterations might be made in the general iorm of theparts described without departing from my invention and hence I do notlimit myself to the precise details set forth but consider myself atliberty to make such changesand alterations as fairly fall within thespirit and scope of the appended claim. I

I claim:

An educational game apparatus including a pair of outer disks,diametrically opposed tabs at the edges of said disks secured togetherdisks in fixed relation, a inovv able disk located betweenthe two outerdisks rotary mounting, said 7 and holding the and having a centralmovable disk having indicia thereon arranged in a circle, one-half ofthe circle having consecutively arranged problems and the restcorrespondingly arranged answers thereto,

. one of said outer disks having openings therein exposing problems andanswers, each answer being diametrically opposite the correspondingproblems, a tab on the movable disk constituting a finger hold to movethe disk, and being limited in its movement by the tabs of the outerdisks, a shutter memberlocated between the movable disk and one of theouter disks and normally coveringthe answer to the problem, and a fingerhold on the shutter projecting beyond the disk and limited in itsmovement in one direction by contact with a pair of the first mentionedtabs.
